I had some issues while ago trying to open a large binary file. Anyway, from file() man page: If mode is omitted, it defaults to 'r'. When opening a binary file, you should append 'b' to the mode value for improved portability. (It's useful even on systems which don't treat binary and text files

FAQ: how to vary the byte offset of a field of a ctypes.Structure

How do I vary the byte offset of a field of a ctypes.Structure? How do I "use the dynamic nature of Python, and (re-)define the data type after the required size is already known, on a case by case basis"? \\\ For example, suppose sometimes I receive the value '\x03hi' + \x04bye' for the struct:

Re: FAQ: how to vary the byte offset of a field of a ctypes.Structure

ctypes.sizeof(a) is still zero, as if ctypes.Structure.__init__ fetches a.__class__._fields_ rather than a._fields_ -- http://mail.python.org/mailman/listinfo/python-list

Re: FAQ: how to vary the byte offset of a field of a ctypes.Structure

""" Thomas, Ouch ouch I must have misunderstood what you meant by "use the dynamic nature of Python, and (re-)define the data type after the required size is already known, on a case by case basis". Do you have an example of what you meant? I searched but did not find. Are those your words? Yes,

Re: FAQ: how to vary the byte offset of a field of a ctypes.Structure

I see that changing self._fields_ doesn't change ctypes.sizeof(self). I guess ctypes.Structure.__init__(self) fetches self.__class__._fields_ not self._fields_. -- http://mail.python.org/mailman/listinfo/python-list

Python 2.5 and WXPython demo's

Hello, I am new (very) to Python and have just down loaded the latest version of Python (2.5) and WXPython (2.8). For some reason I cannot get the WXPython demo to run at all. I run windows XP and it can't find a program to run the demo. Any advice? (apologies if this has been posted before). --
